出砂预测方法研究经历了从简单到复杂、从定性到定量的曲折发展过程。随稠油冷采和出砂管理新技术理论的提出,油气井开采过程中出砂量的预测成为迫切需要解决的问题。对弱胶结砂岩油藏出砂机理和出砂量预测技术的研究进展进行了综合论述。将油气井出砂预测模型分为现场工程法、应力-应变分析模型、蚯蚓洞模型和流固耦合模型,指出不同模型的适用范围及其相互联系,并针对各种预测方法的缺陷提出了研究方向。

Sand production prediction technology has been progressed from simple to complex, qualitative to quantitative. With the development of cold production and sand management, sand prediction is increasinglyurgent. This paper reviews sand production mechanism and different sand prediction methods, including engineering approach, stress-strain model, wormhole model and coupled geomechanicalhydrodynamics model, analyzes the relationship of those models and their applicability, and suggests the future research field based on the comparison of those models.
